SELF-'DETACHING HOLDBACK FOR VEHICLES.

SPECIFICATION forming part of Letters Patent No. 546,061, datedSeptember 10, 1895.

Application filed December 3, 1894. Serial No. 530,640. (No model.)

To all whom it may concern:

Be it known that 1, WILLIAM T. TAYLOR,

of the city of St. Louis and State of Missouri,

have invented certain new and useful Improvements in Self-DetachingI-Ioldbacks for Vehicles, of which the following is a full, clear, andexact description, reference being had to the accompanying drawings,forming a part hereof.

My invention relates to a self-detaching holdback for vehicles; and itconsists in the novel construction, combination, and arrangement ofparts hereinafter described and claimed.

The object of myinvention is to construct a self-detaching holdback forvehicles that possesses superior advantages in point of simplicity,durability, and general efficiency.

In the drawings, Figure 1 is a top plan View of a portion of a shaft,the same having my device attached thereto. Fig. 2 is a top plan view ofthe shafts of a vehicle, showing my devices in position thereon; also aportion of the harness and the holdback-straps. Fig. 3 is a longitudinalsectional view on theindicated line 3 3 of Fig. 4:. Fig. 4 is a sideelevation of my improved device. Fig. 5 is a top plan view of a portionof my device, showing the holdback-strap ring partially disengaged fromthe integral hook on the holdback.

Referring by numerals to the accompanying drawings, 1 indicates theshaft of an ordinary vehicle, upon the inside face of which and at apoint about midway its length myimproved device is attached. This devicecomprises a rectangular metallic plate 2, the same being provided in itsends with apertures or screwholes 3, through which pass ordinary screws4 for rigidly holding the device in its proper position. Formed integralwith the face of the plate 2 and adjacent one end thereof is a hook 5,the front end of which is cut oif square and the, forward portion 6 ofwhich lies parallel with the plate 2. Formed integral with and extendinglongitudinally of the plate 2 in front of the hook 5 is a tubular casing7, in the lower side of which and near the rear end is formed alongitudinal slot 8. Mounted for longitudinal movement within thiscasing 7 is a bolt 9. A manipulating knob or handle 10 passes throughthe slot 8 in the casing 7 and is firmly screwed or seated in said bolt9. An expansive coil-spring 11 is interposed between the rear end of thebolt 9 and the closed end of the casing 7. The action of this coilspringis to always keep the forward end of the bolt 9 in engagement With theface of the longitudinally-extending portion 6 of the hook 5. The casing7 is so located relative the portion 6 of the hook 5 as that one half ofthe face of the spring-actuated bolt 9 within said casing 7 will bearand engage directly against the face-of the longitudinally-extendingportion 6 of the hook 5. The other half of the face of thespring-actuated bolt 9 lies directly in front of the space formedbetween the plate 2 and thelongitudinally-extending portion 6 of thehook5. r

12 indicates the rings carried by the forward end of the holdback-straps13, said hold backstraps 13 being connected to the back straps of theharness 14 in the ordinary manner. The devices so constructed aresecured to the insides of the vehicle-shafts at points usually occupiedby the ends of the holdbackstraps.

When it is desired to position the rings 12 of the holdback-straps 13 inthe hooks .5, the bolts 9 are moved a slight distance rearwardly bymeans of the handles or knobs 10, in order that said rings may bepositioned between the longitudinal portions 6 of the hooks 5. Thecoil-springs 11 now reposition said bolts, and the rings are thusinclosed and held between the hooks 5 and the forward ends of the bolts9. The rings 12 are thus securely held in the desired positions, and aforward pull or jerk must be given said rings sufficient to overcome theresiliency of the springs 11 before said rings 12 can be disengaged fromthe hooks 5. When the animal is unhitched from the vehicle, the ringsare simply drawn forward until they engage directly against the endsofthe bolts 9, that lie directly in the path of travel of said rings 12. Afurther forward movement of said rings moves the bolts 9 rearwardly andallows the rings to be disengaged from the hooks 5. This manner ofdetaching the rings of the holdback-straps from the holdbacks is veryexpeditious and labor-saving,

as there are no straps or buckles to release. Devices of thisconstruction occupy a comparatively small space, are inexpensive, easilyapplied, and complete and practical in all workings and results.

What I claim is In an improved hold-back, a single integral casting 2, ahook 5 extending a distance parallel With said casting and having itsfront end cut off square at a right angle, a springactuated bolt 9having its rear end cut off square at a right angle, with one-half ofits forward end in close contact with the squared end of the said hook,the other half of said squared end being directly in the path of 15 endof said bolt, to positively retract the'bolt 20 without binding of theparts, as setforth.

In testimony whereof I affix my signature in presence of two Witnesse uWILLIAM T. TAYLOR. WVitnesses:
